pass a burden monitor of transport the machine to regulate to adopt the adopt of coal machine amount of coal and make to adopt coal machine and transport the production ability of machine to match mutually;(4)Automatically keying up a control will have the coal rock boundary of certain resolution to identify to spread a feeling machine to combine a calculator control and constitute a coal rock boundary to spread feeling device and coal rock boundary to identify system.Have already apply to physically or just be placed in research at the production currently with experiment the coal rock of stage identify a method and analytical the system mainly have:Remember the intelligence distance control, the analytical and natural D of the vibration frequency chart shoot line, measure dint to cut Chi, radioisotope, Zao voice the infrared ray, radar probe into etc.Remember an intelligence distance to control a coal rock boundary to identify and control system among them an application at most is what foreign main model adopt to automatically key up a technique currently in actually the production.But radars probing into a technique to be think be a kind of coal rock boundary which have application foreground mostIdentify a method;(5)Circulate appearance supervision and manifestation adopts coal machine a data to collect systemCan collect machine parameter:If the Eickhof company SL series adopts coal machine a material to have MICOS68 mineralses to use tiny machine system, main course 10 single submenus include to adopt coal luck to go appearance;Automatically manipulate;Cut to mow a parameter;Lead a parameter, liquid presses system parameter, each examination to order temperature, each electric motor electric current;Water measure, water pressure;Control system soft, hardware model number;Diagnosis, early warning(password) etc., the most protection item can hand over a way to with each other shield through persons machine;(6)The data deliver, agreeable slot control and ground supervisions adopting the coal machine long range communication and work noodles concentration a control technique be the marking of modern mineral well.(7)Expert system and breakdown diagnose data and information from the examination and movement parameter of the supervision, function with former machine maintenance, usage the circumstance carry on a comparison, carry on diagnosis to the healthy movement of machine, can also to particular mistake and recommend the project provide risk valuation.3.4 electricities lead system to adjust to soon develop toward the exchangesThe electricity leads to adopt a lead of coal machines method to press the type of lead the electrical engineering and can is divided into direct current to lead and communicates to lead.The electricity in earlier period leads to adopt coal machine to mostly adopt direct current to adjust soon system.Develop success from the mid 80s of Japan 20 centuries the first set alternate current lead to adopt coal machine and communicate that adjusting soon system is advanced with its technique, dependable sex Gao, the maintenance manage in brief, the price cheap etc. advantage, drive quick expansion application.9The big power electricity expected to develop behind in the age of the o lead3.6 have no chain to lead toward the wheel gear one Chi track the type turn intoAlong with lead continuously enlarge of the dint, sell a round one Chi track types having no chain to lead have already eliminate, wheel gear one chain track types having no chain to lead have already not much use as well, now adopt coal machine have no the chain lead to just and gradually incline toward adoption wheel gear one Chi track type have no the chain lead, this is 1 kind from the wheel gear on selling a track type to turn in to since then have no chain to lead structure, cylinders sell is replace by the Chi track and weld structure to change whole nicety cast or forge, the width enlarge, the stanza is apart from to increase tofrom the 125 mms l 75 mms.4 The local electricity leads to adopt the coal machine research contentsThe local electricity leads to adopt coal machine a representative model and foreign electricity to lead to adopt coal machine to compare and have already near in the total parameter function foreign 20 centuries age initial stage of 9 o level.But some key partses and it the total function, function, orientation scope.etc. still treat further perfect with raise.Particularly on-line work condition monitor, breakdown diagnosis and forecast, the signal deliver and adopt coal machine to automatically control, spread a feeling machine etc. the intelligence turn technique and abroad to compare to still have a bigger margin.As a result the local electricity leads intelligence of adopt the coal machine to turn degree low, the equipments credibility, safety with can support sex worse, the local electricity will lead to adopt coal machine from now onMain research
